Answer:

y = 0.981

Step-by-step explanation:

Given expression:

  • 5.7y-5.2=y/2.5

Solution:

  • 5.7y-5.2=0.4y

Subtract 0.4y from both sides:

  • 5.7y-5.2-0.4y=0.4y-0.4y
  • 5.3y - 5.2 = 0

Add 5.2 to both sides:

  • 5.3y-5.2+5.2 = 0+5.2
  • 5.3y = 5.2

Divide both sides by 5.3:

  • \cfrac{5.3y}{5.3}  =  \cfrac{5.2}{5.3}
  • y = 0.981

Hence, y = 0.981.

5.7y-5.2=y/2.5

Add 5.2 to both sides:

5.7y = y/2.5 + 5.2

y/2.5 = 0.4y

5.7y = 0.4y + 5.2

Subtract 0.4y from both sides:

5.3y = 5.2

Divide both sides by 5.3:

y = 5.2/5.3

y = 0.98113

Cot 2 2x – 4cot2x + 3 = 0
jeyben [28]

x = 9.21° or x = 22.5°

cot²2x – 4cot2x + 3 = 0

Let cot2x = y

y² - 4y + 3 = 0

Factorizing, we have

y² - y - 3y + 3 = 0

y(y - 1) -3(y - 1) = 0

(y - 1)(y - 3) = 0

y - 1 = 0 or y - 3 = 0

y = 1 or y = 3

Since cot2x = y

cot2x = 1 or cot2x = 3

1/tan2x = 1 or 1/tan2x = 3

tan2x = 1 or tan2x = 1/3

2x = tan⁻¹(1) or 2x = tan⁻¹(1/3)

2x = 45° or 2x = 18.43°

x = 45°/2 or x = 18.43°/2

x = 22.5° or x = 9.21°

So, x = 9.21° or x = 22.5°
